Just use the get .../*.xml straight away.

Sorry, I have overwritten your post, instead of responding.

Even if it is an old post, I think it is never toooo late!
I tried the following inside the script file (after connexion):
call echo -d /directory_path/ && mkdir /directory_path/

You will have error messages in the case the /directory_path/ already exists. But the scripts continue running.

Wish it will help.

I have been trying to use this script to check for the presence of a file in the remote directory, but the "ls" command is unable to execute successfully.

The remote file does exist at the root, so I'm wondering if there is an issue in defining the target remote directory as "/". Perhaps there is a syntax handling problem?

Can anyone suggest a possible workaround??

Many thanks!

Please post your full script.

Hi,

I have similar requirements,where in i need to have a condition if folder "XX" already exisit in remote site then dont create new folder else create "XX".

So i am having

But the code just hangs in the

the help file provided in this site does not help.

Thanks

I tested this approach in VB.Net but it does not work. LS command does not seem to be able to check if a file exists.

I am getting too a 'file not found' error regardless file exists or not...

M.R.

What does the log file look like?

I have found a workaround...

When I open WinSCP and connect I am automatically dropped into the root directory where TestFile_DI2010A.txt is but the script states that it can't find it.

Can you give us more details? What do you run? Can you post a screenshot?

I have added a guide for checking for file existence.

This guide contains example for similar problem. I hope it helps you.

Thanks for the reply martin, but my requirement is a bit different, let me explain you that, suppose I need to download multiple files, like ABC.txt, bdc.txt and efg.xls by using the same script, so here I have to check if that particular file exists then only download otherwise log the error that file dose not exists, so for that I need to check the existence of the files, please help me out how can I achieve that with the same script, I really appreciate your help. Thanks a ton..

If the file does not exist, the script fails, so you can catch that already.

Hi,
I am using below script to get the file from the ftp location, I am using winscp in my execute process task of SSIS.

option batch on
# Disable overwrite confirmations that conflict with the previous
option confirm off
# Connect using a password
# open user:password@example.com
# Connect
open user@example.com
# Change remote directory
cd /home/user
# Force binary mode transfer
option transfer binary
# Download file to the local directory d:\
get examplefile.txt d:\
# Disconnect
close
exit

Now befor I start to get the file in my local system I want to check that specific file or file extension actually exists in ftp, if not then want to catch that error.
So for this what are the changes I have to do in my current script. Please let me know, I really appriciate the help for the same.

Looks like you are curing consequence instead of cause.

So, why does not your script hang? Haven't you omitted the "option batch on" command?

Please read FAQ.

I am new to WINSCP and therefore still learning the scripting commands. Is there a way to check if a file exists on a remote machine before downloading it using winscp.com with /command? I have automated my downloads and if the file does not exist, my process "hangs." I would like to check if the file exists before attempting to download. If the file exists, the script would continue, otherwise it would exit.

Any help you can provide would be greatly appreciated.
